쉬트파일을 이용한 교각기초 보강공법{pier footing reinforcement work}Pier foundation reinforcement work using sheet pile

본 발명은 쉬트파일을 이용한 교각기초 보강공법에 관한 것이다.The present invention relates to a bridge foundation reinforcement method using a sheet pile.

일반적으로 교각기초는 시공후 유수의 흐름에 의하여 교각기초의 표면이 침식작용이 발생되며, 이러한 교각기초에 발생하는 침식작용은 교각기초의 강도를 낮출 뿐만 아니라 교각의 수명을 단축시키기 때문에 침식이 발생하는 즉시 보수 및 보강공사를 해야한다.In general, the foundation of the bridge is eroded by the flow of running water after construction, the erosion occurs in the bridge foundation not only lowers the strength of the bridge foundation but also shortens the life of the bridge piers erosion occurs Repair and reinforcement work should be done immediately.

기존에는 침식 발생 교각기초의 표면에 철재 거푸집이나 수중콘크리트를 타설하였으나, 기존 교각기초의 콘크리트와의 접착 분리현상으로 인하여 다시 하자가 발생되는 문제점이 있다.Conventionally, steel formwork or underwater concrete was placed on the surface of erosion-prone pier foundations, but there is a problem in that defects occur again due to the adhesive separation phenomenon of the existing pier foundations with concrete.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로, 교각기초에 가이드파일을 항타하고, 가이드파일 사이에 쉬트파일을 항타한 후, 쉬트파일 내부의 물을 펌프로 양수하고, 쉬트파일의 내부를 터파기한 후, 콘크리트를 타설한 후, 쉬트파일을 인발함으로써, 교각기초의 보강공사후에도 콘크리트 의 접착 분리현상에 의한 재하자를 방지할 수 있도록 한 쉬트파일을 이용한 교각기초 보강공법을 제공하는데 그 목적이 있다.Therefore, the present invention was devised to solve the problems described above, and after guiding the guide file at the foundation of the piers, driving the sheet file between the guide files, pumping the water inside the sheet file with a pump, By piercing the inside of the sheet pile, pouring concrete and drawing the sheet pile, the bridge foundation reinforcement method using the pile pile to prevent the recurrence caused by the adhesion separation phenomenon of the concrete even after the reinforcement work of the bridge foundation The purpose is to provide.

상기한 목적을 달성하기 위한 본 발명에 따른 쉬트파일을 이용한 교각기초 보강공법은 교각기초 주위에 각종 중장비가 장착된 바지선을 띄운 상태로 상기 바지선의 중장비를 이용하여 가이드파일을 항타하는 단계(Ⅰ); 상기 가이드파일의 사이에 쉬트파일을 항타하는 단계(Ⅱ); 상기 쉬트파일 내부의 물을 펌프로 양수하는 단계(Ⅲ); 상기 쉬트파일의 내부를 소정의 깊이까지 크람쉘로 터파기를 실시하는 단계(Ⅳ); 상기 쉬트파일내 터파기에 콘크리트를 타설하는 단계(Ⅴ); 상기 쉬트파일을 인발하는 단계(Ⅵ)로 이루어짐을 특징으로 한다. Pier foundation reinforcement method using the sheet pile according to the present invention for achieving the above object is the step of driving the guide pile using the heavy equipment of the barge while floating barges equipped with various heavy equipment around the bridge foundation (I) ; Driving a sheet file between the guide files (II); Pumping water inside the sheet pile with a pump (III); (IV) discharging the inside of the sheet pile with a cram shell to a predetermined depth; Placing concrete into the trench in the sheet pile (V); And drawing the sheet pile (VI).

이상에서 설명한 바와 같이 본 발명에 따른 쉬트파일을 이용한 교각기초 보강공법은 교각기초에 가이드파일을 항타하고, 가이드파일 사이에 쉬트파일을 항타한 후, 쉬트파일 내부의 물을 펌프로 양수하고, 쉬트파일의 내부를 터파기한 후, 콘크리트를 타설한 후, 쉬트파일을 인발함으로써, 교각기초의 보강공사후에도 콘크리트의 접착 분리현상에 의한 재하자를 방지할 수 있는 장점이 있다.As described above, the bridge foundation reinforcement method using the sheet pile according to the present invention drives the guide file at the foundation of the bridge, drives the sheet pile between the guide files, pumps the water inside the sheet pile with a pump, and After digging the inside of the pile, after pouring concrete, and drawing the sheet pile, there is an advantage that can prevent the retardation caused by the adhesive separation phenomenon of the concrete even after reinforcement of the foundation foundation.

이하, 본 발명을 첨부한 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 1a 내지 1f는 본 발명에 따른 쉬트파일을 이용한 교각기초 보강공법의 시공순서를 도시한 공정도이다.1a to 1f is a process chart showing the construction procedure of the bridge foundation reinforcement method using a sheet pile according to the present invention.

이들 도면에 도시된 바와 같이, 본 발명에 따른 쉬트파일을 이용한 교각기초 보강공법은 각종 중장비(14)가 장착된 바지선(12)을 띄운 상태로 상기 바지선(12)의 중장비(14)를 이용하여 가이드파일(16)을 항타하는 단계(Ⅰ); 상기 가이드파일(16)의 사이에 쉬트파일(18)을 항타하는 단계(Ⅱ); 상기 쉬트파일(18) 내부의 물을 펌프(20)로 양수하는 단계(Ⅲ); 상기 쉬트파일(18)의 내부를 소정의 깊이까지 크람쉘(22)로 터파기(24)를 실시하는 단계(Ⅳ); 상기 쉬트파일(18)내 터파기(24)에 콘크리트(26)를 타설하는 단계(Ⅴ); 상기 쉬트파일(18)을 인발하는 단계(Ⅵ)로 이루어진다.As shown in these drawings, the piling foundation reinforcement method using the sheet pile according to the present invention by using the heavy equipment 14 of the barge 12 in a state of floating the barge 12 is equipped with various heavy equipment (14). Driving the guide file 16 (I); Driving a sheet pile 18 between the guide piles 16; Pumping water in the sheet pile 18 into a pump 20 (III); (IV) discharging the inside of the sheet pile (18) with a cram shell (22) to a predetermined depth; (V) pouring concrete (26) on the trench (24) in the sheet pile (18); The sheet pile 18 is drawn out (VI).

또한, 상기 쉬트파일(18)을 항타한 후 가이드파일(16)을 인발하는 단계(Ⅱ-1)를 추가한다.In addition, after the sheet pile 18 is driven, a step (II-1) of drawing the guide pile 16 is added.

그리고, 상기 크람쉘(22)로 터파기(24)를 실시한 후, 쉬트파일(18)의 내측면에 일정한 두께를 갖는 철판(28)을 설치하고, 상기 철판(28)이 부착된 쉬트파일(18)의 내측면 전체에 비닐시트(29)를 부착하는 단계(Ⅳ-1)를 추가한다.Then, after the trench 24 is performed with the clam shell 22, an iron plate 28 having a predetermined thickness is installed on the inner surface of the sheet pile 18, and the sheet pile with the iron plate 28 attached thereto ( Step (IV-1) of attaching the vinyl sheet 29 to the entire inner surface of the 18) is added.

한편, 상기 쉬트파일(18)을 인발한 후, 교각기초(10)에 세굴방지공(30)을 실시하는 단계(Ⅵ-1)를 추가한다.On the other hand, after drawing the sheet pile 18, the step (VI-1) for performing the scour prevention hole 30 in the bridge foundation 10 is added.

즉, 본 발명에 따른 쉬트파일을 이용한 교각기초 보강공법은 가이드파일(16) 항타단계(Ⅰ); 쉬트파일(18) 항타단계(Ⅱ); 양수단계(Ⅲ); 터파기(24) 단계(Ⅳ); 콘크리트(26) 타설단계(Ⅴ); 쉬트파일(18) 인발단계(Ⅵ)를 순차적으로 시행하여 교각기초를 보강함을 특징으로 한다.That is, the bridge foundation reinforcement method using the sheet pile according to the present invention is a guide file (16) driving step (I); Sheet pile 18 driving step (II); Pumping step (III); Trench 24 step (IV); Concrete 26 pouring process (V); The sheet pile 18 is characterized by reinforcing the foundation of the piers by sequentially carrying out the drawing step (VI).

여기서, 상기 가이드파일(16) 항타단계(Ⅰ)는 교각기초(10)의 주변에 각종 중장비(14)가 장착된 바지선(12)을 띄운 상태에서 먼저 교각기초(10)의 주위에 바 지선(12)의 중장비(14)를 이용하여 가이드파일(16)을 항타하는 단계이다.Here, the guiding step (I) of the guide file 16 is a bar line around the pier foundation 10 in a state where a barge 12 equipped with various heavy equipments 14 is mounted around the pier foundation 10. Step 12 is to drive the guide file 16 using the heavy equipment (14).

상기 쉬트파일(18) 항타단계(Ⅱ)는 상기 가이드파일(16)의 사이에 쉬트파일(18)을 항타한 후, 상기 가이드파일(16)을 인발하는 단계이다.The sheet file 18 driving step (II) is a step of drawing the guide file 16 after hitting the sheet file 18 between the guide files 16.

상기 양수단계(Ⅲ)는 쉬트파일(18) 내부의 물을 펌프(20)로 양수하여 내부를 건조화시키는 단계이다.The pumping step (III) is a step of drying the inside by pumping water in the sheet pile 18 with the pump 20.

상기 터파기(24) 단계(Ⅳ)는 쉬트파일(18)의 내부를 소정의 깊이까지 크람쉘(22)로 터파기(24)를 실시하는 단계이다.The step (IV) of the trench 24 is a step of carrying out the trench 24 with the clam shell 22 to a predetermined depth inside the sheet pile 18.

상기 콘크리트(26) 타설단계(Ⅴ)는 쉬트파일(18)의 내측면에 일정한 두께를 갖는 철판(28)을 설치하고, 상기 철판(28)이 부착된 쉬트파일(18)의 내측면 전체에 비닐시트(29)를 부착하고, 상기 쉬트파일(18)내 터파기(24)에 콘크리트(26)를 타설하여 양생시키는 단계이다.The concrete 26 pouring step (V) is installed on the inner surface of the sheet pile 18, the iron plate 28 having a predetermined thickness, the entire inner surface of the sheet pile 18 to which the iron plate 28 is attached The vinyl sheet 29 is attached, and the concrete 26 is cast and cured in the trench 24 in the sheet pile 18.

여기서, 상기 쉬트파일(18)에 철판(28)을 부착한 이유는 쉬트파일(18)은 대개 요철의 반복형상으로 이루어진 강재로서, 오목부에 철판(28)을 부착하면, 콘크리트의 타설시 콘크리트의 타설량을 줄일 수 있다.
또한 쉬트파일(18)의 내측면 전체에 비닐시트(29)가 부착되어 있으므로 쉬트파일(18)을 원활하게 인발시킬 수 있다.Here, the reason why the iron sheet 28 is attached to the sheet pile 18 is that the sheet pile 18 is usually a steel material having a repetitive shape of irregularities, and when the iron plate 28 is attached to the recess, Can reduce the amount of pour.
In addition, since the vinyl sheet 29 is attached to the entire inner surface of the sheet pile 18, the sheet pile 18 can be smoothly drawn out.

상기 쉬트파일(18) 인발단계(Ⅵ)는 쉬트파일(18)을 인발하는 단계이다.The sheet pile 18 is drawn out from the sheet pile 18.

상기 쉬트파일(18)을 인발한 후, 교각기초(10)에 세굴방지공(30)을 실시한다.After drawing the sheet pile 18, the piercing base 10 is subjected to the scour prevention hole (30).

도 1a 내지 1f는 본 발명에 따른 쉬트파일을 이용한 교각기초 보강공법의 시공순서를 도시한 공정도.Figure 1a to 1f is a process chart showing the construction sequence of the bridge foundation reinforcement method using the sheet pile according to the present invention.
